AUTOMATIC EXHIBITION DEVICE.

. automatic exhibition device with endless bands moving over rollers, said bands being provided with suitable means for holding the cards. According to the present invention the bands are provided with hooks, the points of which project upward, thus catching and carrying upward the card introduced by a slide. In this way it is possible to arrange the aperture for the introduction of the cards at about the height of a persons hand and the viewing surface opposite the persons head, thus affording convenience in use.

Further essential characteristics of the present invention are the especial form of construction of the coin locking device and the especially suitable form of slide for introducing the cards; further, a new coupling device for the transport roller with indicating device to show when any one band is ready to receive a card; and finally, a delivery device operated by the introduction of a coin.

Reference being had to the accompanying drawing, Figure 1 shows a cross section, Fig. 2 a longitudinal section, and Fig. 3 details of the device according to the present invention. Fig. 4 shows a cross section of a modified form of construction, and Figs. 5 and 6 a front view and plan view of the device for delivering the cards.

' The form of construction according to 3 Figs. 1 and 2 is as follows: The endless bands 1, 2, 3 are moved upward behind the viewing surface a by means of rollers f, f driven continuously by clockwork or other suitable means. The bands are provided at suitable intervals with hooks a pointing upward, adapted to engage with correspondingly positioned holes of the cards 6, thus moving said cards upward behind the view surface a. The hooks of the several bands Specification of Letters Patent.

are so situated in respect to one another, that one card appears in almost its whole extent (Fig. 2, band 3), the other about (band 2) and the third about E; (band 1). The slides 12. are operated by the single coin channel p in such a manner that, after a coin has been introduced, always that slide springs up of which the band shows the next free field. The mechanism to attain this result consists of the following parts: On the shaft 8 a loose hub 25 is provided for each of the lower rollers f or slides h, said hub being provided with an arm 2', having at its end a hook it adapted to engage with a suitable recess of the appertaining slide box 7L, thereby holding said slide and preventing the introduction of a card. The hubs t are further provided with pivoted lugs 0, having pins 4) engaging in holes a of a slide rod n, the latter being spring or weight pressed and connected with the coin balance 1" by means of the bell crank w. On the circumference of the rollers f are situated pins 9 at intervals corresponding to the intervals of the hooks 0 of the single bands. When the coin channel 1) is empty the coin balance will occupy the position shown by the dotted lines in Fig. 2 and the slide rod a will be in such a position that the pivoted lugs 0 cannot engage wit-h the pins g. If now a coin is introduced into the channel 72, the coin balance 1' is depressed, the coin being held in position by a pin a: of the lever-arm y (Fig. 3). By the depression of the coin balance a" the slide rod n is moved toward the right to the position shown by the full lines in Fig. 2, so that the pivoted lugs 0 come to lie in the path of the pins 9 of the rollers f. The pin 9 which is at the moment nearest the lugs 0 will then engage with the appertaining pivoted lug 0 and rotate the hub if under control of the spring 33, thus causing the arm 2' with hooked end a to release the appertaining slide box h, which latter is then pressed outward by a spring 31. The card is now placed on the slide and the latter pushed in. In the meantime the money has been caused to fall down by the pressure of the lever 2' against the pivoted beam is, which is connected with the arm :1 thus causing pin m to release the coin, which then falls into the coin receptacle. The coin balance now resumes its initial position, the

plished by mechanical means simultaneously 3 rod n slides again to the left, lug 0 and pin 9 cease to engage, and the beam and lever z are moved by weights 32 into their former positions, so that the hook to again engages with the slide box it, thus locking the latter in position.

The slide mechanism may also be constructed as shown in Fig. 4. The front a of the introduction box is here curved and inclined inwardly. The box is pivoted on an axis 4 and is providedwith a handle 5. Below each introduction box it a detent lever 8 is pivoted at 6 and pressed by the spring 7 said lever engaging with a pin 9 of the appertaining lever arm '5, the latter corresponding in construction and operation to Figs. 1 and 2, as already described. When one of the lever arms i is depressed, its pin 9 moves the appertaining detent lever 8 into the position shown by dotted lines in the drawing, so that the nose 1O releases the bottom of the box it and the latter descends by its own weight making free a slit into which the card 6 can be introduced. The box 71 is then lifted by the handle 5 and closed, thus causing the card 6 to slide forward so that it can be grasped by the hooks c, as already described.

In the form of construction according to Figs. 1 and 2 all the rollers have the same speed of rotation the driving-power being applied to the roller shaft 11. The device may, however, be so constructed, that each pair of rollers has a different velocity, the appertaining bands therefore also moving each with a different velocity. This may be attained, as shown in Fig. 4, by providing a separate driving shaft 12, connecting with the lower rollers by means of cog wheel gearing 13, 14, 15 or chain 16 or similar suitable means, the gearing being so chosen that different speeds of rotation ensue for each roller. The speeds may, for instance, be so chosen, that band 1 makes a complete journey in one hour, band 2 in two hours and so forth. Further, each band may be provided with an indicating device, which shows, when the slide appertaining to this band can be opened by the insertion of a coin. The simplest form of such indicating device will be the provision of laterally sit-- uated signs or dots on each band, 17, Fig. 2, which register with similar dots 17 on the glass (4 immediately before the mechanism of the appertaining roller is in a position for operation.

The delivery of the cards can be accomwith the insertion of the coin, as shown in the construction according to Figs. 5 and 6. The cards or card packs 18 are arranged alternately to right and left, one upon the other, as shown in Fig. 6. In front, a roller 22, vertically movable in the guides 19, presses in such manner on the pack, that the uppermost card 18 remains free. At the back a spring 20, or a weight, presses the pack against the roller 22. The latter is pro vided with suitable formed pieces 21, abutting against the free card or card pack. Roller 22 is operated by a spring-pressed lever 23, either by hand or mechanically, said lever being generally locked in its position and automatically released after the insertion of a coin. On the right and left of the guides 24, delivery boards 25, 25 are arranged. If, after insertion of a coin and consequent release of the lever 23, the latter is moved in the direction of the arrow (Fig. 5) the uppermost card pack will be pushed out by the piece 21 onto the delivery board 25. The roller 22 then occupies the position 22 and is in a position to deliver another pack onto the opposite delivery board 25. The further operation of the device, for instance, opening of the slide h, and so forth, does not take place until the uppermost card ack has been delivered, as above described.
